A sterile, flat surgical cutting instrument, usually made of high-grade stainless steel, with a serrated edge designed for attachment to a dedicated powered saw used for cutting bone/tissue during orthopaedic or oral surgery. This device is designed with the cutting teeth arranged in an arc at the distal end pointing directly forward. It cuts when the blade is powered in a rapid oscillating (side to side) movement. This type of blade allows a frontal cutting action to be applied within a restricted area. This is a single-use device.
